RFFM4527
RFMD + TriQuint = Qorvo
Wi-Fi Low Noise Amplifier
4900MHz to 5925MHz
Product Description
The RFFM4527 is a low noise amplifier (LNA) designed for Wi-Fi
802.11a/n/ac systems. The integrated input and output 50Ω match
minimizes layout area in the customer’s application, reduces the
bill of materials and manufacturability cost. Performance is focused
on a balance of low noise and gain that increases the receive
sensitivity. The RFFM4527 integrates a bypass path that enables
a defined gain step. The device is provided in a 1.6mm x 1.6mm x
0.5mm, 6-pin DFN package.
Package: DFN, 6-pin,
1.6mm x 1.6mm x 0.5mm max
